Vintage C.T. Altwasser German Hand Painted Ashtray -- rare

Vintage and unusual C.T. Altwasser porcelain hand painted ashtray. Base approx 3 3/4". Brown shades with gren leaves an yellow fruit. The design is on all three sides. Looking down at the top it looks like chips but it's where the paint missed during painting. No chips, cracks. Markings on bottom are hard to read (see pic). The C.T. Altwasser logo came out fine but cannot decipher the rest. Pay Pal. U.S. only.
